  Research Notes:

The Historia Francorum names (in order) "Hugonem qui cognominatus est Magnus, Henricum, Robertum, Odonem" as the four sons of King Robert and his wife Constance. Rodulfus Glauber names "Heinricus rex…germanium suum Rotbertum" when recording the latter's installation as duke of Burgundy by his brother. His mother supported him as candidate to be consecrated associate king in 1027, in place of his older brother Henri who was supported by their father. His father named him heir to the duchy of Burgundy in 1030.

He was installed as ROBERT I Duke of Burgundy in 1032 by his brother King Henri I. Comte d'Auxerre in 1040, when he conquered the county after Hugues Bishop of Auxerre died in 1039. He lost it after the 1060 council of Autun which ended his war with Nevers. “Robertus Burgundie dux” renounced rights “in villa...Gilliacus...” in favour of Saint-Germain-des-Prés by charter dated 22 Sep 1040, subscribed by “...Elie conjugis eius...”. “Robertus dux Burgundiorum cum uxore mea Helia” donated “terram...Villare Bichet...in pago Belnensi” to Saint-Germain-des-Prés, with the consent of “filiorum nostrorum Hugonis et Henrici”, by charter dated to [1043/44]. “Robertus dux et duo filii mei Hugo et Henricus” renounced rights to revenue from land “in Gilliaco” in favour of Saint-Germain-des-Prés by charter dated 2 Feb 1053.

The necrology of Cîteaux records the death "VIII Id Mar" of "Robertus…dux Burgundie". The necrology of Molesme records the death "XV Kal Apr" of "Robertus dux Burgundie et Ermengardis uxor eius". There is some mystery surrounding his death: a narrative by Pierre de Saint-Julien deacon of Chalon records that “Robertus dux” died “nuper dedecorose” in the church of Fleury-sur-Ouche, without providing further details. ¹
